AIR5317 establishes the foundation for developing a successful APU health management capability for any commercial or military operator, flying fixed wing aircraft or rotorcraft. This AIR provides guidance for demonstrating business value through improved dispatch reliability, fewer service interruptions, and lower maintenance costs and for satisfying Extended Operations (ETOPS) availability and compliance requirements.
This SAE Aerospace Information Report (AIR) provides insight and guidance into the best practices for implementing a health management capability for Auxiliary Power Units (APU) installed on commercial or military aircraft. With the considerable advancement of prognostics and health management (PHM) tools and capabilities in the past 10 years, operators expect that the value proposition for such a system can easily be demonstrated for APUs. This AIR aims to assist operators in building the PHM capability such that the value can be achieved.
